lBe it known that I, CHARLESA. PHILLIPS,

aa citizen ofthe United` States, 4residing fat cityandcounty of San Francisco and State of California, have invented `certain new and Auseful Improvements in Chiropractic Tables, of which the "following is a specification.

The present invention relates to improve- `ments in *chiropractic tables andthe inven tion has among its objects A'to-provide` 'a table whereby the legsupport is adapted for adjustment to A"and `from thechest support; one wherein the edge of thelchest support adjaycent the` head, rest `isp capable of Vyielding movement to ladmit of theadjustment of the 'vertebrae at the base of the neck. `Other obiects of the `invention are to provide a y Inovel form of pivotal construction for the legsupport and chestsupport and to in- Vcorporate in `connection therewithvariable tension means and locking mechanism. A further object is to provide a head rest .p adiustablfeasto height and .variable as to `tilistance'from wone edgeA of *the chest support. OtherV 'obiectswill appear from a readingmf the `detailed description of the' preferred embodiment hereinafter i set forth.

With thejabove mentioned and other ob- 3l)` jects in view, the invention consists lin the novel constructionand combination of parts hereinafter described, `illustrated inthe ac- "companying'drawings and set A"forth in the claims hereto appended, it," being understood that various, changesin vthe `form, propor- `within Vthe fscopeot the claims-Hinay be. re-

v1-sbted to without departing from the spirit .or'sacrificing any of theadvantages of -the inver i tiron. v

`Figure V5 is a transverse sectional 'view taken on the line 5-f5 Lott Fig. 1 through a Apivotal point of the legsupport.

In thedrawings, lindicates the elongated rectangular base having a raised A'portion 2 at one end and within said raisedvportion there is mounted thehead rest.standard guide'. y The guide 3 is adapted for vertical adjustment, the head rest standard it curved at its upper end at 5, and wliich'pivot'ally mounts as at 6,` the head restf? prefer- `ablv carryingcushioned lor yieldable upper surface- 8. The member 4: is retained Yinits adjusted position by, any suitable means `such as the adiustable j am screw 9, the outer end of which is bent asat 10` and weighted as at 11.

At theopposite end the base 1 isrprovided with the rectangular raised portion 12, the side members `13 of whicharefpe'aked as at 14. r' At their apex a fulcrum rod'15 passes therethrough `and extendsthrough thesside members 190i the rectangular v:[iiame120` of the adjustable leg support.` This latter member consists of y a bottom y,boardjor l'portion 22 secured `tothe frame l2O and which on its upper *surface the board` mounts a spring cushion 23. :A coiled spring 2li/'resists the downward pivotal movement of `the front edge Alot the yleg supportand said spring is united at its lower end preferably Mto the rear wall of the member12 as at 25.

To lock-the leg support frcmpivot'al movement andat the desired angle, lprovide a pivoted link 26 depending from the member 22 and its lower apertured end passes through they bifurcated guide 27. A lock ipin 28 operatedby a bell crank -leverj29 is vadapted for reception within the apertures in the ,plink 26. The `bell crankjlever. is

V'mounted on'the plate 30 `and is normally held in raised position by a spring `31. The

jfree end of the lever which is weightedmas at 32, extends through the `wall of the "member 12 and through a notched plate '33; the lower notch 34 of whichisadapted to receive the 'free'endjotthe bellcrank and k'hold tliepin '28;"in its retracted 'position.

To "natie the adjusting@ transgene port and its mounting 12 longitudinally of the base 1, the base side walls on their respective inner faces are grooved as at 35V and within the same are received guide members 36 secured to the side walls 13 of the member 12. The finishing plate 37 extending forwardly from the member 12, is adapted to telescope beneath a corresponding finishing plate 38 rigidly secured to the side walls of the base 1 in advance of the normal position of the adjustable leg support. r chest support is pivotally mounted to the uppermost extension 39 of the raised portion 2 of the base and the same is constructed in the following manner. A substantially triangularframe consisting of the horizontal leg portion 40, vertical leg portion 41 and inclined leg portion 42 is fulcrumed at one corner to pivot on 'the' transverse rod 43 mounted in the side walls of the member 39. This construction is'mounted with the frame overhanging facing the forward edge of the leg support. The respective members 40, 41 and 42 forming the ends of the frame, are connected by the transverse connecting members 44, 45 and 46. A cushion bottom board 47 rests on the upper edge of the horizontal legs 40 of the triangular frame and at one end is hinged as at 48 to the edge of the transverse member 45, the member 47 falling shoft of overlying the fulcrum member 43. In continuing the member 47 over and beyond the fulcrum member 43, I employ the* parallel strips 49, the adjacent edges of which are downwardly inclined as at 50 away from each other, the upper meeting edges of the strips are hinged together as as 51 to permit the downward flexible move- Ament of the strips over the downwardly beveled edge 52 of the member 45. rIhis construction lends fiexibility to that edge of the chest support facing the inner edge of the head rest. Over the upper surface of the edge 52 and board 47 is positioned a cushion 53 similar in construction to the cushions 8 and 23. respectivelv, used in connection with the head rest and legs support. The springs 54 of the cushion 53 assist in normally maintaining the surface of the strips 50 in a plane parallel with the surface of the board 47.

n To control the pivotal movement of the triangular `frame in one direction, I provide a transverse stop 55 connecting the side members at the base 1 and at a point below the fulcrum 43. With this stop is adapted to contact the lower edge of themembers 41 on the swinging of the long leg of the frame to a horizontal position. To lock the chest support in this position and to prevent the Asame from pivoting on the fulcrum 43. I

emplovfthe pivoted frame 56 fulcrumed as at 57 between thewalls ladapted Ifor operation by vthe weighted lever ofthe base 1 and port position-ed between theV head-.rest

58 extending exteriorly of the base 1. The movement of the frame 56 to contact with the member 46 locks the triangular frame of the chest support against the angle rod 55 and precludes pivotal movement thereof until the frame 56 is swung free of the member 46. To oppose the pivotal movement of the chest support, I provide the coilspring 58 connected through the adinstable eye bolt'59 with the member 46. The other end of the spring 58 is connected through an adjustable eye bolt 60 with-a lever 61- fulcrumed as at 62 within the base 1 and the free end of the lever extends outwardly through the sides of the base 1 and is provided with an operating handle 63. A notched and slotted plate 64 through which the lever 61 extends provides a means for holding the lever in different angular positions to regulate tension on the spring58.

Bv this construction it will be observed that all controls for the different supports extend from the base at one side. also that the legs support is adapted for adiustment to and from the Chest support. and that the head rest due to the bent end of 'the member 4 is adapted for movement to and from the forward edge of the chest support by axially rotating the support 4 ofthe head rest. It will also be understood that the legs support is adapted for pivotal movement opposed bv the tension of spring 24 and is also capable of being locked in a horizontal or angular position. It is also possible to lock the chest support from pivotal movement and to varv the tension of the spring opposing the pivotal movement when such movement is permitted'. It will be understood that by making the forward edge of the chest support of such construction as will permit the same to bend downwardly. that the work of the operator in performing certain adjustments is materiallv expedited.

Having thus described mv what I claim as new and desire by Letters Patent. is:

1. A chiropractic table including a base. a legs support at one end thereof. ahead rest at the other end thereof. a chest support positioned between the head rest and legs support. the latter including a frame pivotally mounted to swing on la horizon'- tal axis. the frame including a cushioned bottom board provided at its edge facing the head rest with a plurality of transverselv disposed sections. and means for hingedlv invention, to secure connecting the sections to swing downward- 12 lv on a horizontal axis.

2. A chiropractic table including a base. a legs support at one end thereof. a head rest at the other end thereof. 4'a -che'st supand legs-support," the vlett-"er-lincludinga#frame pivotally mounted to swing on a horizontal axis, the frame including a cushioned bottom board provided atfgis edge Jfacing the head rest with a plurality of transversely disposed sections, means for hingedly connecting the sections torsvving downwardly on a horizontal axis, and yielding means for normally maintaining the hinged sections in substantially the same plane with the botv tom board.

In testimony yvhereof I have signed my name to this speeication.
